Righteous Among the Nations (Hebrew: חֲסִידֵי אֻמּוֹת הָעוֹלָם ḥasidei ummot ha'olam) is an honourific used by the State of Israel to describe all of the non-Jews who, for purely altruistic reasons, risked their lives in order to save Jews from being exterminated by Nazi Germany during the Holocaust. The term originates from the concept of ger toshav, a legal term used to refer to non-Jewish observers of the Seven Laws of Noah. Source: Wikipedia (en)
